Embodiment 1

[0029] Preparation of the suspension:

[0030] In terms of parts by weight, the mass of methyl methacrylate and butyl acrylate was mixed to obtain 50 parts of mixed monomers, and 8 parts of ammonium persulfate aqueous solution with a mass fraction of 40% was prepared as an initiator. Add 14 parts of mixed monomers to the four-necked flask, stir for 2 minutes, then add 2 parts of initiator to the four-necked flask, react for 10 minutes, then mix the remaining mixed monomers with the initiator to obtain suspension.

[0031] Preparation of self-crosslinking acrylate emulsion:

[0032] Use a dropping funnel to drop the suspension into the above four-necked flask at a dropping rate of 5mL / min, put the four-necked flask in a water bath, heat up to 85°C, keep the temperature for 40min, and remove the water from the four-necked flask. In a bath, adjust the pH value of the self-crosslinking acrylate emulsion to 7.0 with ammonia water with a mass fraction of 25%, cool naturally to roo...

[0042] Preparation of the suspension:

[0043] In terms of parts by weight, the mass of methyl methacrylate and butyl acrylate was mixed to obtain 55 parts of mixed monomers, and 9 parts of ammonium persulfate aqueous solution with a mass fraction of 40% was prepared as an initiator. Add 15 parts of mixed monomers to the four-necked flask, stir for 3 minutes, then add 2 parts of initiator to the four-necked flask, react for 11 minutes, then mix the remaining mixed monomers with the initiator to obtain suspension.

[0044] Preparation of self-crosslinking acrylate emulsion:

[0045] Use a dropping funnel to drop the suspension into the above-mentioned four-necked flask at a dropping rate of 6 mL / min, put the four-necked flask into a water bath, heat up to 87°C, keep the temperature for 43 minutes, and remove the water from the four-necked flask. In a bath, adjust the pH value of the self-crosslinking acrylate emulsion to 7.5 with ammonia water with a mass fraction of 25%. Aft...

Embodiment 3

[0055] Preparation of the suspension:

[0056] In terms of parts by weight, the mass of methyl methacrylate and butyl acrylate was mixed to obtain 60 parts of mixed monomers, and 10 parts of ammonium persulfate aqueous solution with a mass fraction of 40% was prepared as an initiator. Add 16 parts of mixed monomers to the four-necked flask, stir for 4 minutes, then add 3 parts of initiator to the four-necked flask, react for 12 minutes, then mix the remaining mixed monomers with the initiator to obtain suspension.

[0057] Preparation of self-crosslinking acrylate emulsion:

[0058] Use a dropping funnel to drop the suspension into the above four-necked flask at a dropping rate of 7 mL / min, put the four-necked flask in a water bath, heat up to 90°C, keep the temperature for 45 minutes, and remove the water from the four-necked flask. In a bath, adjust the pH value of the self-crosslinking acrylate emulsion to 8.0 with ammonia water with a mass fraction of 25%, cool naturally...

Abstract

The invention belongs to the technical field of decorative material preparation, and particularly relates to a preparation method of a sound-absorbing wall cloth. The method comprises the steps that methyl methacrylate and butyl acrylate are adopted as raw materials and subjected to initiating polymerization to obtain a self-crosslinking acrylate emulsion, dioctyl phthalate and halloysite nanotubes are mixed to obtain a reaction product, then the self-crosslinking acrylate emulsion is spray-coated onto the surface of a honeycomb fabric loaded with titanium dioxide, coating of a filling liquidis conducted after standing and solidification, and the sound-absorbing environment-friendly wall cloth is obtained through drying and calendering. According to the method, the cotton thread pore density of the honeycomb fabric made of cotton threads is large, and pores are sealed after spray coating of the self-crosslinking acrylate emulsion to form closed pores, so that the honeycomb fabric preliminarily has a certain sound insulation capacity; in addition, the titanium dioxide shows higher catalytic activity under visible light, the catalytic degradation concentration of organic pollutantscan be reduced, the method has great superiority compared with a mode of directly doping activated carbon and other adsorbing materials in a wall cloth, and the application prospect is broad.

Description

technical field [0001] The invention belongs to the technical field of preparation of decorative materials, and in particular relates to a preparation method of sound-absorbing wall covering. Background technique [0002] With the continuous development of social economy and the continuous improvement of people's living standards, modern people have higher and higher individual requirements for interior wall decoration. At present, when people are decorating houses, there are choices of wall painting, wallpaper and wall covering. In order to ensure the fast decoration, people abandon the original work of wall painting and turn it into wallpaper, The veneer of the wall covering, and the wallpaper will be damaged due to moisture or accidental forceful contact during use, and the service life is relatively short. Therefore, the wall covering has gradually become the choice of people's wall decoration. Wall cloth, also known as wall cloth, is a fabric for pasting walls, which i...
